LA'ENGHER, on nmrnuns'r, new YORK, AssIGnon TO A. KIMBALL com- .PANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK TAG Application filed November 17, 19 28. Serial'No.

This invention relates to price tags of the variety known as pin tickets, this name being commonly applied to that class of tags which are provided with wire staples which are adapted to penetrate the goods to which they are to of the staples are bent over dental removal.

It is an object of the present invention to provide a pin ticket and a method of making the same in which the ends of the staples which penetrate the goods are so formed as to present a substantially smooth, rounde end, whereby the danger of injuring the goods or the hands of the users because of cont-act with jagged edges of the ends of ordinary staples is substantially eliminated.

It is an additional object of the invention to prevent accito corrodible material is exposed at theends of the staples, thus additionally protecting the oods against damage from rust stains, etc. Other objects and advantages of the invention will appear hereinafter.

A preferred embodiment or the invention selected for purposes of illustration is shown in the accompanying drawings, in which,

Figure 1 is a top plan view of a pin ticket,

Figure 2 is a side elevation,

Figure 3 is an enlarged side elevation of one end of a square cut staple prior to coatinw treatment, and

*igure 4: is a similar view after coating.

Referring to the drawings, a pin ticket ,1 is illustrated in Figures 1 and 2 in which the wire staple 2 is secured to the end of the ticket in the conventional manner. According to the present invention, the ends 3 of the wire from which the staple is formed are preferably square cut, as illustrated in Fig ure 3, according to methods which are well known in the art in order that the said ends may be as free as possible from burrs or other jagged projections which would tend to damage the goods or injure the fingers of the users. Preferably the said square out is made prior to the insertion of the staple in the ticket, although it will be understood that the wire may be cut and inserted in the ticket, and the ends of the staple may be subbe attached, after which the ends rovide a pin ticket in which only non sequently treated-to if desired. 7 j I r v Y After the staples are cut, the ends are preferablyrounded as illustrated in Figure 4 This rounding'is preferably accomplished by coating the ends of the staples with suitable material. In order to form the desired rounded end, the coating operation is preferably performed by dipping the ends of the staples into the coating material while the said material is maintained in fluid condition, for it has been found that there is a tendency for the coating material to'collect on the severed surface of the wire in globular form, that is, with a smoothly rounded surface t. By suitably controlling the degree of fluidity of the coating material the size and shape of the said globule may be varied as desired. v

' A coating of metal, preferably tin, because of the non-corrodible properties of this metal, has been found particularly satisfactory but other metal or non-metallic material of suitable hardness may be used.

provide the square cut VV hen tin is used the ends of the staples are first treated with a suitable flux and are then dipped in the molten metal, preferably several times in succession. In this manner a globule of tin is formed on the severed surface-of each-end of the staple which provides a substantially round surface which readily penetrates the fabrics or other material to which it may be desired to attach the tickets. The metal coating also covers any slight irregularities of the end surface of the wire, thus giving the ends of the staples a smooth surface which will not damage the goods and which will not injure the hands of the users. 7

In the case of metallic coating, the desired degree ofsfiu'idity of the molten metal may be obtained by suitably controlling the temperature. It has been found that good results may be obtained where tin is used as the coating metal if the metal is maintained at a temperature of approximately v570 degrees F.

It will be noted that where the coating material is non-corrodible, such as tin, the entire surface of the endof the pin is protected,

and the goods to which the tickets are attached are protected from rust stains, etc., which sometimes result with the use of ordinary staples.

5 It is to be understood that while staples having square cut ends are particularly well adapted for coating, for reasons described above, staples cut in other ways maybe 7 coated as described herein to advantages, for

10 a coating in any case covers some of the roughness incidental to cutting,'and also provides a non-corrodible surface which p e- Vents rusting.

It is also to be understood that the inven 1 tion may be variously modified and embodied within the scope ofthe subjoinedsclaims.

I claim as my invention: s

A pin ticket comprising a tag and wire staple secured thereto, the said wire staple 20 having a legprojecting from the tag, and having a rounded penetrating end formed of protective material of a cross-sectional area nowhere materially exceeding thecrosssectional area of the-wire.

I 2 2. A Ipin ticket comprising-a tag and wire staple secured thereto, the said wire staple having a leg projecting from the tag, and having a square cut end, the saidsquare cut end being rounded and protected by a globule -3 ofiprotectrve material of a cross-sectional area nowhere materially exceeding the crosssectional area ofthe wire. a

3'. The method of rounding and protecting the ends of pin ticket staples which comprises dipping said endsrin fluid coating material, withdrawing said ends and holding them in position to permit a-glohule'of saidfluid coating material to form and ,harden'thereon, and maintaii'iing said vfluid coating material at the time ofdipping said staple ends at a degree offiuidity such that the formed globule has across-sectional area nowhere material-1y exceeding the cross-sectional area of the staple. V 4. Themetho of rounding and protecting .tion to permit a globule of tin to form and harden thereon, and maintaining said molten tin at the time of dippingsaid staples at a temperature of approximately 570 F.

In testimony whereof, I have signed 'm name to this specification this 15th day of November, 1928.
